All mountains around the world have native and non-native species that are expanding their ranges quite dramatically; however, little research has been conducted towards understanding the long-term redistribution of species and the effects of global change on biodiversity.


The Afromontane Research Unit (ARU) on the University of the Free State Qwaqwa Campus – as part of the Mountain Invasion Research Network – has secured a two-year EU Horizon 2020 project under the Department of Science and Innovation, which will be looking at the mechanisms underlying the success and impact of range-expanding species on biodiversity and ecosystem functioning.

On Monday 19 July 2021, the ARU took a few of its researchers on a scenic helicopter ride to the summit of the Drakensberg for an alpine field-experiment site inspection of the Mont-aux-Sources peak, one of the highest sections of the Drakensberg range. This site has been identified for the project which the research unit will be leading on mountain research.

ARU Director, Dr Ralph Clark, said the project would explore the effects of global change, biological invasions (when species invade new geographic regions), as well as climate and land-use change. He said experiments were needed to explore the various possibilities and to test the extent to which species respond to experimental treatments. The project would therefore be conducting experiments for two years using open-top chambers – causing an increase in temperature of 3 or 4 degrees to what you find naturally – on plant species from lower down to the top of the mountain, to see how they function. “This will give us an idea of whether they will be able to survive in global warming scenarios. If temperatures get warmer, we might start seeing a lot of plants up here that we wouldn’t otherwise find here.”

Dr Clark said little is known about the long-term monitoring of species distribution and the effects of global change. Implementing the project in the Maloti-Drakensberg alpine area will therefore put the area in the global mountain research arena. The elevational gradient in the Maloti-Drakensberg Mountains provides space to explore the key processes underlying the variation in species elevation with climate change. “One of the things we don’t know much about are alpine systems. We are hoping to establish a long-term alpine research site and try to add as many studies as we can. The more science we can bring up here, the more we can know about mountain life. What happens on mountains has a lot of impact on social dynamics.

“This project is looking to see what is driving range expansion. Every mountain has its own context. In the Swiss alpine, fires are not a big factor, but fires are one of the biggest factors on our mountains. Some of our native and non-native species are therefore fire-driven, so as fire increases, you might have them spreading faster.”

Prof Melanie Walker to spearhead international organisation
2014-06-02

 
Prof Melanie Walker has just added another phenomenal achievement to her illustrious academic career. Members of the international Human Development and Capabilities Association (HDCA) have elected her to the leading role of Vice-President.

Founded in 2004 by Amartya Sen and Martha Nussbaum, the HDCA is a global community of academics and practitioners. Together, they seek to build an intellectual community around the ideas of human development and the capability approach. Ultimately, the association strives to drive these ideas into the policy arena.

With members living in over 70 countries world-wide, the HDCA promotes research across a wide field of disciplines. These range from economics, philosophy and development studies to health, education, law, government, sociology and more.

In her new role, Prof Walker will be working closely with the renowned philosopher, Prof Henry Richardson of Georgetown University, USA. He is currently President-elect of the association. “My election as Vice-President will enable me to work closely with Henry and the Executive Committee to build on the first successful decade of the association to strengthen its reach and responsiveness to researchers, practitioners and policy makers,” Prof Walker says. “It is a tremendous honour to have been elected and a wonderful challenge for the next three years, personally and professionally. It will also place a significant spotlight on the human development and capabilities research I am leading at the UFS.”

Annually, the HDCA organises an international conference. This year celebrates a decade of successful symposiums and will take place in Athens. Eight Kovsie graduate students and researchers from the UFS’s Centre for Research on Higher Education and Development have had their papers accepted.
